| Abstract: | Modified polylactic acid was prepared using lactic acid, bisphenol A and phthalic anhydride as main materials. Performance and structure of the copolymers were evaluated and tested respectively. The infrared spectroscopy testing results proved that aromatic ring structure was added into the main chain of polylactic acid. The heat shrinkage testing results showed that the thermal stability of modified polylactic acid was increased. |
